Police received a 911 call Sunday morning from a woman who said her 20-year-old boyfriend had a mental illness, shortly after he crashed her mother's car at the beginning of a shooting rampage that left a Weymouth Police officer and an elderly woman dead.

Dispatch audio obtained by The Patriot Ledger on Tuesday indicates that the girlfriend of the man accused of fatally shooting a Weymouth police officer and an elderly bystander Sunday morning had called 911 to warn police that her boyfriend suffered from a bipolar disorder and was prone to manic episodes.

The call to Weymouth dispatchers apparently came after Emanuel Lopes, 20, had crashed a BMW registered to the girlfriend’s mother into an SUV while taking a turn from Main Street onto Columbian Road around 7:30 a.m. Sunday. Police say Officer Michael Chesna was responding to the hit-and-run crash when he spotted Lopes, got out of his cruiser and confronted him with his gun drawn.

Police say Lopes threw a rock at Chesna’s head from 10 to 12 feet away, knocking the officer to the ground and causing him to drop his gun. Police say Lopes then picked up the gun, stood over Chesna and fired about ten rounds, half of them aimed at the officer’s head.

Police say Lopes was shot in the leg moments later by an officer who found him standing over Chesna’s body with the gun in his hand. Lopes was able to run off and the officer can be heard in the dispatch audio shouting for help.

“Officer down! We need more help here. He has a weapon,” the officer, identified in a police report as Officer Sean Murphy,” can be heard saying.

Later, he makes another plea: “Officer down! Office down! Get as much help here as we can!”

The audio suggests that there were some confusion immediately after the shooting, with some officials believe that Chesna had been stabbed, not shot. But as the gravity of the situation became clear, more officials began communicating over the phone rather than using the radio, which anyone can listen to.

“Deputy, I can't call right now,” one officer can be heard saying. “Worst case scenario right now.”

Police say after Lopes left the street where Chesna was shot, he fired three more rounds into the picture window of a Torrey Street home, fatally wounding 77-year-old Vera Adams. He is due to be arraigned in Quincy District Court today on two counts of murder.

Lopes is scheduled for arraignment Tuesday afternoon in Quincy District Court. He had scheduled to be arraigned on Monday on two counts of murder,but officials determined that he was "medically unavailable." Lopes was shot in the leg shortly after allegedly firing 10 shots at Chesna, an Army veteran and father of two who had been responding to a report of a hit-and-run crash.

Police say Lopes later fired three rounds through the picture window of a home on Torrey Street, hitting 77-year-old Vera Adams once in the chest.
